Sen. Elizabeth Warren kicked the 2020 White House race into high gear on New Year's Eve when she announced the formation of a presidential exploratory committee.The announcement made clear that Warren is in the race for the Democratic nomination, but by forming an exploratory committee, she is technically still one step short of officially becoming a presidential candidate.An exploratory committee is a vehicle by which candidates for federal office can "test the waters" of a bid before officially entering a race.It's a mostly technical distinction that allows candidates to form a committee and begin raising and spending money on limited campaign activities like polling and outreach. And exploratory committees aren't initially required to file reports with the Federal Election Commission, at least until a candidate's bid becomes official by FEC standards.That happens, 892

Such an important day at the United Nations, so much work and so much success, and the Democrats purposely had to ruin and demean it with more breaking news Witch Hunt garbage. So bad for our Country!— Donald J. Trump (@realDonaldTrump) September 24, 2019 267

PRINCE GEORGE COUNTY, Md. -- A man was stabbed to death Monday at a Maryland Popeyes after what appears to have been an argument over the restaurant's re-released chicken sandwich, police said.The victim, a 28-year-old man, was stabbed outside the restaurant around 7p.m., Prince George's County Police spokeswoman Jennifer Donelan said at a news conference Monday. He had been in line for a chicken sandwich when he and another man got into an argument, which spilled onto the street, Donelan said. Police believe the argument began over someone cutting in line."For you to get that angry over anything ... and to develop into this type of violence, again, is a very sad and tragic day," Donelan said.Officers who arrived on the scene applied lifesaving measures until the man was transported to a local hospital, where he was pronounced dead, Donelan said.Police are still looking for the suspect. Donelan asked the suspect and people who were in restaurant at the time to reach out to detectives."We are looking for a male, and that male knows who he is," Donelan said. "He knows what he did here tonight, and he needs to do the right thing and he needs to step up and turn himself in."CNN has reached out to Popeyes for a statement. 1248

Scans of the lungs of the sickest COVID-19 patients show distinctive patterns of infection, but so far those clues offer little help in predicting which patients will pull through. For now, doctors are relying on what’s called supportive care that’s standard for severe pneumonia.Doctors in areas still bracing for an onslaught of sick patients are scouring medical reports and hosting webinars with Chinese doctors to get the best advice on what works and what hasn’t.One thing that’s clear around the globe: Age makes a huge difference in survival. And one reason is that seniors’ lungs don’t have as much of what geriatrics expert Dr. Richard Baron calls reserve capacity.“At age 18, you have a lot of extra lung capacity you don’t use unless you’re running a marathon,” explained Baron, who heads the American Board of Internal Medicine. That capacity gradually declines with age even in otherwise healthy people, so “if you’re an old person, even a mild form can overwhelm your lungs if you don’t have enough reserve.”Here’s what scientists can say so far about treating those who become severely ill.HOW DOES COVID-19 HARM THE LUNGS?The new coronavirus, like most respiratory viruses, is spread by droplets from someone’s cough or sneeze. The vast majority of patients recover, most after experiencing mild or moderate symptoms such as fever and cough. But sometimes the virus makes its way deep into the lungs to cause pneumonia.Lungs contain grapelike clusters of tiny air sacs called alveoli. When you breathe, oxygen fills the sacs and passes straight into blood vessels that nestle alongside them. Pneumonia occurs when an infection -- of any sort, not just this new virus -- inflames the lungs’ sacs. In severe cases they fill with fluid, dead cells and other debris so oxygen can’t get through.If other countries have the same experience as China, about 5% of COVID-19 patients could become sick enough to require intensive careHOW DOES THAT DAMAGE APPEAR?Doctors at New York’s Mount Sinai Health System analyzed 121 chest CT scans shared by colleagues in China and spotted something unusual.Healthy lungs look mostly black on medical scans because they’re full of air. An early infection with bacterial pneumonia tends to show up as a white blotch in one section of one lung. Pneumonia caused by a virus can show up as hazy patches that go by a weird name -- “ground glass opacities.”In people who get COVID-19 pneumonia, that haze tends to cluster on the outside edge of both lungs, by the ribs, a distinctive pattern, said Dr. Adam Bernheim, a radiologist at Mount Sinai.As infection worsens, the haze forms rounder clusters and gradually turns more white as the air sacs become increasingly clogged.HOW TO TREAT THE PNEUMONIA?There are no drugs so far that directly attack the new coronavirus, although doctors are trying some experimentally, including an old malaria treatment and one under development to treat Ebola.“The best treatment we have is supportive care,” said Dr. Aimee Moulin, an emergency care physician at the University of California Davis Medical Center.That centers around assistance in breathing when the oxygen levels in patients’ blood starts to drop. For some people, oxygen delivered through a mask or tubes in the nose is enough. More severely ill patients will need a breathing machine.“The goal is to keep the person alive until the disease takes its course” and the lungs begin to heal, explained Mount Sinai’s Dr. Neil Schachter.The very worst cases develop an inflammatory condition called ARDS -- acute respiratory distress syndrome — that floods the lungs with fluid. That’s when the immune system’s attempt to fight infection “is going crazy and itself attacking the lung,” Baron explained.Many things besides the coronavirus can cause the condition, and regardless of the cause, it comes with a high risk of death.WHAT ELSE IS IMPACTED?Severe pneumonia of any sort can cause shock and other organ damage. But in a webinar last week, Chinese doctors told members of the American College of Cardiology to watch for some additional problems in severe COVID-19, especially in people with heart disease. The worst off may need blood thinners as their blood starts to abnormally clot, and the heart itself may sustain damage not just from lack of oxygen but from the inflammation engulfing the body.Another caution: The sickest patients can deteriorate rapidly, something a hospital in Kirkland, Washington, witnessed.Of 21 patients who needed critical care at Evergreen Hospital, 17 were moved into the ICU without 24 hours of hospital admission, doctors reported last week in the 4639

Prosecutors say California attorney Michael Avenatti has been rearrested for alleged bail violations. Prosecutors in New York late Tuesday notified a judge that federal authorities in Los Angeles have notified them that Avenatti was arrested in California for alleged violations of the conditions of his pretrial release. Avenatti is scheduled for trial next week in Manhattan federal court. That trial pertains to allegations that he extorted Nike for up to million. He has pleaded not guilty. But he also faces trial later this year in Los Angeles on charges that he defrauded clients. 603
